2. Something has gone wrong with the issuance of the SSL cert, or our vendors have put an additional security check in place before issuing the certificate.

3. Your DNS Records on the Cloudflare dashboard are 'grey-clouded' and you are bypassing our proxy. For Cloudflare to present our certificates you need to be passing through an 'orange-clouded' DNS record.

4. Cloudflare SSL only applies up to first level subdomains. For example, you might not be seeing any errors on the root domain (yoursite.com) and www (www.yoursite.com) over https://, but get errors on second level subdomains (test.www.yoursite.com). This can be fixed with a Cloudflare Dedicated Certificate with Custom Hostnames.
